The specific embodiment
Fig. 1 shows the hydraulic motor-brake equipment of II type loop distribution, and the project organization of this self-propelled vehicle-brake equipment is known basically in the prior art.What people knew is, brake equipment 1 includes the braking force intensive 7 that 3, one of foot brake pedals have master-brake cylinder 8, and this master-brake cylinder 8 is provided with a brake fluid tank 9.Braking force intensive 7 is strengthened the braking force that is applied by chaufeur and is produced a brake-pressure on foot brake pedal 3, this brake-pressure is by brake piping 12 guiding car side brakes 11.
Different with the brake equipment of knowing is, this brake equipment includes an additional valve 10, and this valve is arranged in master-brake piping 12 of driven, and its effect is to reduce the brake-pressure that applied by chaufeur.Here show two valves 10, left valve wherein only is installed under the situation of back-wheel drive, right valve only is installed under the situation of f-w-d, two valves 10 are installed under the all-wheel powered situation.This valve 10 is connected with controller 2 and is triggered by the deceleration share of this controller according to chaufeur-deceleration wish and motor 14.
In service in regeneration, motor 14 is as generator operation.Produce a drag torque to promote the deceleration of automobile at this this motor.Attempt to produce the high as far as possible share of total reduction in principle, so that the maxim of recuperated energy by electrical generator 14.In addition part will be caused by service brake 11 if present.
Generator operation is subjected to the restriction of the capacity of vehicle power.If vehicle power can only hold seldom electric energy or even can not hold electric energy at all, the deceleration share of motor 14 must correspondingly reduce so, and the share of service brake must improve.
The deceleration of chaufeur expectation can be for example by brake parameters sensor displacement pickup 5 or measure for example by means of the pressure sensor 6 (for example so-called pre-pressure sensor) that is arranged in the brake circuit.Controller 2 for example obtains information about the electric energy that is produced by electrical generator 14 by mixture controller 13, and the energy state that this mixture controller is determined vehicle power is capacity in other words.Controller 2 and 13 also may be incorporated in the unique controller.
The deceleration share of service brake 11 is by total reduction wish verz FShare verz with electrical generator 14 HIn draw.Be suitable at this:
verz B＝verz F-verz H
For regulating this numerical value, reducing valve 10 triggers (perhaps regulating) by controller 2, the feasible brake-pressure (P that is predesignated by chaufeur Vor) correspondingly reduce.
Valve 10 preferably by beat be triggered.Can realize very simple like this and hang down into favourable decompression.
Fig. 2 shows the hydraulic brake system of the X type loop distribution with a plurality of additional reducing valves 10.Wherein components identical use with Fig. 1 in identical Reference numeral represent.Exterior electric wiring arrange basically with Fig. 1 in the same, but, dispense exterior electric wiring layout for the reason of removing.
Different with Fig. 1, in each brake piping 12 of driven wheel, all be provided with independent valve 10 here.In having the automobile of f-w-d, valve preferably only is arranged in the brake piping 12 of front-wheel (being the valve on two the right in the drawings), in having the automobile of back-wheel drive, valve preferably only is arranged in the brake piping 12 of trailing wheel (valves on two left sides), and in having the all-wheel powered automobile, valve is preferably in the brake piping 12 that is arranged on all wheels (as shown in the figure).
In braking procedure, require to have additional deceleration by service brake 11, at this moment valve 10 will be triggered about as described in Fig. 1 as the front.The brake-pressure of effect preferably is adjusted to a rated value on drg 11.
